Class 4 (Locobase 10014)
Data from the website celebrating the activities of Colonel Hollman Fred Stephens and in particular the PD & SWJR -- [
], last accessed 26 March 2009.
These two radial tanks (works numbers 2695-2696) were delivered right at the end of 1907 (Boxing Day, actually) s the Earl of Mount Edgecumbe and Lord St Levan. Although later owned by the London & South Western Railway, the only succeeeding numbers they actually bore were the 757-758 assigned to them by the Southern Railway after Grouping.
